Fix a goof where KVM fails to re-initialize the set of supported VM types, resulting in KVM overreporting the set of supported types when a vendor module is reloaded with incompatible settings. E.g. unload kvm-intel.ko, reload with ept=0, and KVM will incorrectly treat SW_PROTECTED_VM as supported. Fix a similar long-standing bug with supported_mce_cap that is much less benign, and then harden against us making the same mistake in the future.
